200 Series K-Arm Stainless Steel Spider Fitting for Point-Supported Glass Curtain Wall
The 200 series K-arm spider fitting is the core connector of point-supported glass curtain wall systems, used to secure glass panel corners back to the supporting structure. Its K-claw design arranges the fixing points in a compact K-shaped arm layout, distributing structural loads evenly across adjacent glass panels while keeping the facade visually lightweight and uncluttered.
Built on a 200 mm center distance, this K-arm configuration suits corner and edge panel positions where a full four-arm cross spider is not required. Precision investment casting in stainless steel gives the hub and arms a smooth, consistent form, so facade contractors receive a repeatable fixing detail that lines the panel grid up cleanly across a large elevation.

Installation & Usage
The spider is fixed to its back support through the central hub, and each glass corner is engaged with matching point-fixing hardware. Installers first loosely position the spider, align the panel corners to the drawn grid, and confirm gasket seating before final tightening. Protective film should remain on polished faces during handling, and the stainless surfaces should be cleaned after installation to remove fingerprints and construction residue.
Quality Assurance
Every K-arm spider fitting is 100% inspected before shipment for casting soundness, thread integrity and surface finish. Material test certificates are available on request to support project specifications.
Applications
- Point-supported glass curtain walls
- Glass canopies & skylights
